DEVICE FOR SUPPORTING AND ADJUSTING SCREENS OR UNDERCASINGS FOR THE CYLINDERS OR ROLLERS OF CARDlNG-ENGINES.

SPECIFICATION forming part of Letters Patent No. 485,679, dated November 8, 1892.

Application filed July 1, 1892. Serial No. 438,731. (No model.)

To all whom it may concern:

. Be it known that I, WILLIAM PITT CANNING, acitizen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Devices for Supporting and Adjusting Screens or Undercasings for the Cylinders or Rollers of Carding-Engines, of which the following is a speciication, reference being had therein to the accompanying drawings. Y

Myinvention relates to carding-engines, and in particular to the'undercasings or screens and the adjusting devices therefor which are employed in connection with the cylinders or rollers of such machines.

` My invention consists, mainly, in the combination, with an undercasing or screen of a carding-engine-for example, the main-cylinder undercasing or screen-0f certain devices whereby the position of the undercasing or screen may be adjusted relatively to the cylinder or roller with which it co-operates, all substantiall y as shown in the accompanying drawings and described in the following specification, and as particularly pointed out and defined in the claims at the close of the specification.

In the accompanying drawings, Figure 1 is a plan view of the undercasing 0r screen of the main cylinder of a carding-engine; and Fig. 2 is a view of one of the side frames of a carding-engine, an undercasing or screen, and adjusting devices embodying my invention, the undercasing being in section on the line a a in Fig. 1. Figs. 3 and 4 are side and edge views, respectively, of the adjusting -lever shown in Fig. 2. Figs. 5 and 6 are views, taken at right angles to each other, of one of the the eyebolts or hangers which I employ in connection with the undercasing for the purpose of supporting the latter and adjusting its position. Fig. 7 is a perspective of one of the adjustable stands, which are shown in Fig. 2 applied to the side framing of a card. Figs. 8 and 9 are views, taken at right angles to each other, of the adjustable stand, which is provided with bearings for the ends of the screw passing through the adj usting-lever shown in At 1 1 are portions of one side framing of a carding-engine, and at 2 is a screen or undercasing. At 3, 4, and 5 are stands, which are adjustably secured to the side framing 1 by bolts or screws 6, passing through slots 7 in the feet or portions of said stands, which are applied to the side framing. At 8, 9, and 10 are eyebolts or hangers, the eye ends whereof engage with pins on the undercasing, while the threaded ends thereof pass through slots in the laterally-projecting portions of the stands 3, 4, and 5, respectively, and receive thereon nuts 11 above and below the said portions of said stands, which nuts may be turned as desired and as may be required in moving the eyebolts or hangers endwise for the purpose of adjusting the undercasing. The eyebolt or hanger 8 at the right-hand side of the undercasing in Fig. 2 has the eye thereof engaged with a pin 12, projecting from the undercasing at a point adjacent to the righthand edge thereof, and the said eyebolt or hanger is arranged so as to be radial, or approximately so, to the cylinder or roller adjacent to which the undercasing is placed. The eyebolts or hangers 9 and 10 at the left-hand side of Fig. 2 both have the eyel portions thereof engaged with the pin'l, projecting from the undercasing. The eyebolt or hanger 9 is vertical, or approximately so, while the eyebolt or hanger 10 is arranged so as to be radial, or approximately so, to the cylinder or roller adjacent to which the undercasing is placed. I support the undercasing between the points at which the eyebolts or hangers 8, 9, and 10 are connected therewith by means of a lever 14. The said lever 14 has one end lthereof slotted longitudinally, as at 15, and

through the slot p asses a pin or the like device 16, projecting from the end of the undercasing. The lever 14 is pivoted at 17, and in the `other end thereof is formed a screwthreaded hole 18, into which is turned a screw 19, the ends whereof will usually project on opposite sides of the end of the lever. The said end of the lever is placed between the shoulders or bearing-surfaces 2O 21 of the stand 22, and preferably the opposite ends of the screw 19 will both take bearing against the shoulders 2O 2l. The foot of the stand 22 IOO is slotted, as at 23, for the., passage o f the screw 2 4, by. whichitV is ad'j'ustably-secured to the side framing 1. The lever 14 and connected parts enable me to support the undereasing at an intermediate point between the eyebolt or hanger 8 and the eyebolts or hangers 9 and 10, and the settingand adjusting devices employed, as shownin connection with the said lever enable me to accurately adjust the intermediate portion of the undercasing relatively to the surface of the cylinder or roller adjacent to which the undercasing is placed. The use of, the lever 14 is necessitated by the desire to mount the main cylinder` of the carding-engine in bearings which are as low as possible on the side framings of the machine.

In carding-engines having1 the main cylinder mounted as low as in those now builtby me there is not suiicient room below the middle portion of the undercasing to permit of the use of eyebolts or hangers, such as 8, 9, and 10, and the stands with which the latter are connected. Moreover, were similarly-disposed eyebolts or hangers to beemployed at the intermediate points in a carding-engine having the main cylinder bearings located at `made in. sections and; hinged together, of

a convenient height above the side trainings. the adjustingdevices for the eyebolts or hangers still would have to be so'disposed as to` render them practically inaccessible. The use of a lever 14, disposed substantially asindicatedin the drawings and having an arm.. thereof extended into the wider space existing adjacent to the rear edge of the undercasing, enables me to provide proper support for the undercasing even in a cardingengine in which the main cylinder is set so lowV as that the under side of the undercasing comes into very close proximity to the il'oor, and. enables me to place the setting` or adjusting devices where they maybe conveniently reached and manipulated. For the purpose offacilitatingthe adjustment of the undercas.- ingV relatively to the surface oi the cylinder or roller adjacent to which it is placed'I prefer toA construct the said undercasing in two sections be employed in practice at the opposite end thereof.

I claim as my invention- 1. The combination, with an undercasing, of a lever inoperative connection therewith and an adj usting-screw whereby to move the lever and set the undercasing, substantially as described.

2,` Thecombination, withan undercasing, of hangers and adjusting devicestherefor at the front and rear sides ot the" saidI undercasing, a lever in operative connection.. with the said. undercasing intermediate the said hangers, and a screw whereby to movey the lever in setting the undercasing," substantially as described.

3. The combinatiomwith an undercasing hangers connected with theundercasing and provided with adjusting devices, as described, a lever in operativel connection with the un- `dercasing. intermediateY the hangers,r and a screw whereby to move the lever 1n setting the undercasing, substantially as described. 4. The combination, with the undercasing,

.of a lever in operative connection therewith,
